Large filters for large sensors

The larger the sensor and the faster the optics, the more important filter clear aperture becomes. The 2-inch format reduces the risk of vignetting.

Practical note

Plan backfocus and threaded mechanical connections before buying. With reducers and flatteners, every millimetre of optical path matters.
